Sean Carroll is the scientist who will not let you have a soul and will not let you have nothing. A theoretical physicist at Johns Hopkins who spent his career on the arrow of time, quantum mechanics, and the foundations of cosmology, he arrived at a philosophy he calls poetic naturalism: there is one natural world, and there are many true vocabularies for describing it, each valid in its own domain. Temperature is real even though no atom is warm; agency is real even though physics is deterministic; consciousness is real even though it is made of the same stuff as a rock. Carroll spent decades arguing that the reductionist who says “merely atoms” and the dualist who says “something more” share the same mistaken premise—that only one level of description may be called real.
